But who will draw anteaters and fancy dolphins?

I like seeing your drawings : >

Perhaps need long break? yer stuff is really quite wonderful, the colors, the composure, everything is really great! It can be you are having struggles, and if art gets in the way or makes it harder, one perhaps need break, very long break, to deal with those things, but perhaps maybe one day you can pick it back up? And even if you don't, that's still understandable, it's not your job/responsability to create things for people, but never stop dreaming about the things you were creating, always dream/think about the things, then they can live on, if in your mind.
Huggies, hope things get better soon, if you need a poke or to talk let me know, I'm almost always on skype, very often yes!

Wow do I know this situation well and still trying to get myself past it.
An emotional breakdown during my time in art school about 8 years now over my worth as an artist and if I'd made the wrong choice of going to school for it due to the poor and lackluster grades I pulled on all my assignments. Just felt everyone including students who hadn't drawn much if any before freshman year were improving faster than me so that just made me feel worse.
Thought dropping out for awhile to clear my head and stop adding to my debt would help but it has just left me feeling a bit empty cause this was a long time dream for me.
I'd say take a break from all art stuff for awhile then whenever you feel like it just do little doodles here and there, nothing major, just something that may at some point trigger the desire to fully create stuff again.
Also could take up another medium for a bit, that may help. Just saying stuff I've dabbled in that has slowly moved me forward towards enjoying creating stuff.

You had been away for a very long time and only recently have been back. Maybe that's been a bit overwhelming lately?

Ultimately it's up to you, but I'd hate to see your talent and skill disappear. I'd recommend taking a break and enjoying things in your life that you weren't sure you had time for. Just refresh your mind, that tends to help with blocks of any kind.
